Overtourism in Iceland

I had a chance to visit Iceland twice.  The first time was in June of 2013 and then a second time October 2015.

From what I am reading, I don't know if I want to go again.

Iceland is suffering the same headaches that Costa Rica has experienced (two visits starting 2000).

Too many people, low cost carriers leaving all lead to a problem in Iceland.

Just like the AT.
